65. Tutorial – Pan Sharpened Image – Automated Method________________________________________________________________This tutorial will walk you step-by-step through the recommended method forproducing a panchromatic image from Landsat band files. For this example, I willstart with Landsat files in .L1G format. This is a common format for Landsat dataon the GLCF website. The other format is GeoTiff. Here is the set of files that Idownloaded for this example:Notice that there are three band files, i.e. the B10, B20 and B30 files for band1(blue), band2 (green) and band3 (red), respectively. The B80 file is thepanchromatic band. The three band files are about 53MB each and thepanchromatic file is 215MB. I downloaded the metadata file in .htm format. Thisis the format that PANCROMA TM reads.The next step is to launch PANCROMA TM and open the data files, in the order…B10; …B20; …B30; and …B80. (You do not have to open the .htm fileexplicitly as PANCROMA TM will find it automatically if it is in the same directoryas the band files.) (Make sure to select the ‘.L1G’ file type from the drop downlist in the file open dialog box.)IMPORTANT NOTE: Make sure that all five files are in the same directory.If you have opened your files correctly, your screen should look something likethe figure below.303
